Programming Beyond Practices
- If your code is a mess, then people will assume that your attention to detail in how the app was coded is also a mess - perception
- Teams should adopt formatting rules and follow them
- Automated tools help with the process
- “Code formatting is important”
- Code formatting has a direct affect on maintainability and extensibility of code over time
- Try to keep max length around 500 lines long and smaller is better - FitNesse app is in this range
- Tomcat and Ant - several thousand lines long and at least half are over 200
- Newspaper metaphor - read it vertically - headlines at the top detail increases as we go down the page
- Separate concepts with blank lines
- Closely associated code should be grouped together so it’s dense
- Concepts (methods) that are closely related should be grouped as closely together as possible to keep from hunting through files
- Variable declarations should be as close to their usage as possible
- If the methods are short, then the variable declarations should be at the top of the function!
- Control variables for loop should be defined within the loop
- Instance variables should be declared at the top of a class
- When one function calls another, those should be close vertically in the file
- Conceptual affinity - when methods do similar things or are named similarly, they should also appear close to each other
- Vertical ordering of methods - the caller should be first, then the callee, and that method’s callee, etc…on down the page
- Death of Macbook Pro?
- The beginning of a new awesome era?
- How wide should a line be?!
- In the popular projects examined, it appeared that 40% of lines were between 20 and 60 characters
- Another 30% of lines were less than 10 characters…
- Author suggests that beyond 100-120 is careless
- Put spaces on both sides of an assignment operator (equals sign)
- Don’t put spaces between the function name and the parens
- DO put spaces after individual arguments / parameters in a list - shows they are separate
- Also use spacing to indicate the precedence of operations - think of spacing in math equations with several parentheses - author calls it out for order of precedence, I actually don’t like this one - I prefer grouping with parens
- Lining up variable declarations, names, types - found that it was distracting to the “story” of the code….I agree
- Hierarchically lining up code based on it’s scope - super important
- Author would sometimes condense multiple lines into one (like a get; set;) eventually set it back for readability (breaking indentation)
- What about for PRINT statements in SQL???
while statements - indent the semicolon on the next line…otherwise they’re hidden
- Follow the team’s formatting rules…don’t go vigilante
- He threw in Uncle Bob’s formatting rules
